A) 30.22 g NaCl x 1 mol NaC l = 58.4430 Molar mass (g) NaCl=0.5171 mol NaCl

B) 0.5171 mol NaCl x 1 mol Na = 1 mol NaCl=0.5171 mol Na

0.5171 mol NaCl x 1 mol Cl = 1 mol NaCl = 0.5171 mol Cl

A sample of sodium chloride (NaCl) has a mass of 30.22g.

A) I have to calculate the number of moles of NaCl in the sample. B) calculate number of moles in each element in NaCl C) calculate the number of each element in NaCl.

I have a and b done im confused on c.

    The third question requires you to solve for the weight of sodium (Na) and weight of Chloride (Cl) from the calculated moles of each element Na, and Cl.

    So, you need to multiply the calculated moles of Na with its molar mass (23 g / mol) to get the answer for Na. And multiply the calculated moles of Cl with its molar mass (35.45 g/mol) to get the answer for Cl.
